Rotational molding pertains to a plastic production technique that makes hollow stress-free products. The procedure uses high temperatures and bi axial rotation to come up with seamless, one piece objects that have many different shapes, colors and sizes. This procedure is also called rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl forms.

The function that makes this unique from other plastic manufacturing methods because no pressure is called for. It also has few rivals when it comes down to the production of large hollow products which are long lasting and inexpensive.There is a variety of product lines that are produced by this process including large water tanks, automobile materials, intricate designed medical products, recreation equipment, toys, canoes, commercial equipment among many others.This is due to the flexibility in regards to style and shapes that the process makes

Benefits of Using Rotomolding to Manufacture Plastic Products

– Relatively low tooling costs. When compared to other plastic manufacturing processes in Bogota NJ 7603, it is a cheaper way of making plastics. This is because apart from the fact that no pressure is required, the cost of mold preparation is low.

– A wide array of design options. There is no limit to the kind of design one may want to create. The rotomoulding process therefore allows for the manufacturing of products that have complex shapes for different purposes.

– Size. The process provides room for the manufacturing of products of any size, large or small. As mentioned earlier, it has few competitors when it comes to the making of large tanks at low costs.

– Low risk. Due to the low costs of creating a mould, the process allows for test runs before one can decide whether to do mass production. It therefore minimizes the risk of losing a lot of investment.

– Durable products. The process allows for even coating of the mould with the heated polymer, giving the product a wall with uniform thickness. It also gives the option of double coating for increased durability. Sometimes metal inserts are placed inside the mould to further strengthen the product.

– Environmentally friendly. There is no waste that could have a negative impact on the environment because the products that cannot be used are reground and reused as polymer.

Examples of Products Made by Rotational Molding

Rotocasting is a very versatile process, making it possible to create a variety of products for different industries.

Furniture– We have plastic cabinets, chairs and tables made from this form of moulding.

There are numerous New Jersey plastic products also that have been made for the marine industry, lighting, waste storage and transportation, kayaks etc.

Few Disadvantages – There are nominal disadvantages that have been associated with rotocasting. For instance:

– The process is relatively slow when compared to injection moulding.

– There is a limitation when it comes to the type of raw material you can use. Only poly based and nylon polymers can be used.

– The process comes with an increased cost because the polymer has to be ground to powder form before use. These limitations are often overlooked considering that the process is still relatively cheap and offers more in terms of variety when it comes to the finished range of products.

Remember – There are new developments and discoveries that are being made as the world of plastic manufacturing in Bogota New Jersey continuously. For instance, tests are being done to see whether there are other materials that can be used for this process. But so far, rotomoulding offers a good option for the production of a wide range of inexpensive plastic products.

The Rotomolding Method in Detail

This moulding technique has been used since ancient times for creatingvseverl products. Egyptians for instance, utilized rotocasting solutions in the creating of ceramics. The Swiss were also using this rotation technique to generate hollow chocolate eggs. Some plastic products in the USA were manufactured utilizing this technique some time between 1940 and 1950. The process has however taken long to catch on because it was considered to be a rather slow process

1. Mold preparation. A fixed volume of polymer in particle form is packed into a hollow mold. The mould is usually built from cast aluminium or sheet steel component. The color wanted for the end item is pre compounded into the polymer. The most often used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this type of plastic production.

Pre-heating of the oven starts, and it can be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mould with the powdered polymer is then sealed and inserted inside the oven.

2. The heating up and fusion step. Once placed into the oven, the mold is revolved on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The spinning is done gradually, about 20 spins per min. One thing that is crucial at this moment is the period of time the mould will spend within the oven. If it stays to long, the component will lose value and strength, creating a faulty item. If it is extracted from the oven prematurely, the polymer will not have melted correctly, which creates bubbles in the finished product.

3. Mold cooling down. When the component has sufficiently spent the enough of time in the oven, it is then extracted for cooling. This may be done by air or water, or sometimes a mixture of both which generates a cool mist. When the product cools, it reduces slightly for ease of removal from the mould. This is yet another procedure that depends a lot on the correct timing, since rapid cooling decreases the material too quickly, causing bending of the product.

4. The un-loading or de-molding step. As soon as the material inside te mould has cooled correctly, the molder handling the process can then take out the completed product from the mould. The function is repeated from the beginning, making a series of exact product lines.
